Your program's defined limits HLASM Toolkit Feature Interactive Debug Facility User's Guide GC26-8709-07 |

IDF considers "your program" to be any location within the
initial target program module, and any more program modules that
you have defined.
The origin and size of the programs known to IDF are displayed in the Target Status window, when open. Whenever possible, IDF tells you if your program is about to branch to a location outside its defined limits. This is often useful in finding a "wild branch", for example to location zero. If you have specified the TRACEALL option, IDF considers the defined limits of your program to begin at location zero and extend upward to the address specified in the VMSIZE word of NUCON. Thus when you specify TRACEALL, you can trace through all of virtual memory. Take care if you attempt to trace through protected (read only) storage. If you specify the RISK option, IDF considers all of memory to be within your program's defined limits. Thus you could attempt to step through code in a DCSS that is actually above the address specified in the VMSIZE word of NUCON. |
